Cold Air Intake
Built from hand-fabricated, high-grade metal and featuring a 4.5" mandrel-bent intake tube, HSPs Cold Air Intake reduces turbulence and increases airflow. The included heat shield box protects the system from underhood heat, ensuring cooler and denser air reaches the turbo. On the dyno, this intake has shown gains of up to 20 HP and 58 lb-ft of torque. Cooler intake air means more power and better overall engine performance.
